When sourcing potato chips, you must prioritize shelf-life stability and packaging integrity. Ensure the supplier uses Nitrogen-flushing technology (MAP - Modified Atmosphere Packaging) to prevent oxidation and maintain crispness. The moisture content should be strictly controlled below 2% to prevent microbial growth. Additionally, verify the oil type used (e.g., palm oil, sunflower oil, or high-oleic oils) as this affects both the nutritional profile and the rancidity point during long-term storage.
